So, I'm just curious - what was the first high wing tricycle multi engine plane with gear that retracted into the engine pods - in other words, where did the Commander design come from?
The B-24 is close, but it's a shoulder wing and the gear retracted into the wings, not into the engine pods.
The Percival Merganser (1946) is the earliest example I've found. https://en.wikipedia.org/wiki/Percival_Merganser
I think the first high wing retractable gear single engine plane was the Cessna CR-3, a very short-lived 1933 design. Wikipedia says it's a shoulder wing but the wing is flush with the top of the fuselage. https://en.wikipedia.org/wiki/Cessna_CR-3
Anyone know any earlier ones?
